Port 443 is used for which service?

Explanation:
Port numbers map to specific services, and 443 is the standard for secure web traffic. HTTPS is HTTP wrapped with TLS/SSL to provide encryption, integrity, and authentication, so when you browse with a secure connection, the data travels on port 443. HTTP itself uses port 80, not 443. SNMP uses UDP ports 161 and 162 for network management, and IMAP uses 143 (or 993 for IMAPS) for email retrieval. So the port 443 designation clearly aligns with Hypertext Transfer Protocol Secure (HTTPS).
